Abstract
ZnO and CuO nanoparticles have attracted a lot of attention lately because of their special qualities. In terms of structure and characteristics, this group of nanostructures is the most preferred one. The research was done on biosynthesis ZnO-CuO nanoparticle. The objective of this study was to synthesize ZnO-CuO nanoparticles, characterize them, and use them as an antibacterial agent against Staphylococcus aureus. The media of ethanolic extract of Psidium guajava L. in alkaline solution were used to biosynthesize ZnO-CuO nanoparticles. The tools used to examine the functional groups and physical structure of ZnO-CuO nanoparticles include FTIR spectroscopy and X-ray diffraction. Using the well agar diffusion method, ZnO-CuO nanoparticle suspension was used as an antibacterial agent. Wavenumbers of the functional groups of Zn-O and Cu-O groups are 507.28 and 617.22 cm-1, respectively. ZnO-CuO nanoparticles' crystallite size was calculated to be 2.33 nm. Staphylococcus aureus may be resistant to the ZnO/CuO nanoparticles' antimicrobial effects. ZnO-CuO nanoparticles have a greater inhibitory zone than ZnO or CuO nanoparticles.
